Configuration

By default, cassandra is setup to listen on localhost. If you want to move
your clients to another host, you're going to need to change which
interface it binds to in the storage-conf.xml. You should also change the
seed address.

Node Auto-Discovery

The list of hosts you pass to the client is only used to auto-discover all
the nodes in your cluster. You don't need to give the client a list of
all of your nodes.
